cheese, fried foods, and those with citrus or high acid content are not good for fissure suffers.
as with any diet, the first thing is to read up on it and then take what may be appealing, if anything, and customize it to you. as in the case of seeds and nuts, it would make more sense if you are going to eat them, to use the machine at the store (if there should be one) and make it into a creamy spread.
you can still eat lots of foods you love but you may have to either eat them in their natural form or turn them into mush/liquify in order to avoid anything that is not smooth going down.
macrobiotics has lots of amazing tips in just how you eat, not only in what you should eat.
probably one of the most interesting tips that really helped is that cereal that you eat in the morning -- it must be hot/warm and without milk (dairy), sweetners (sugar or artificial). and to expand on that, having a hearty soup such as miso soup with shrimp, tofu, and the much needed seaweed or a vegetable soup with barley or brown rice along with some hot green tea or simple hot water over a month will do wonders for your digestive system and how things come out.
there are secrets to be explored in macrobiotic principles but i am neither novice nor expert to guide you.
all i can say is that when your body is in harmony with the seasons and temperature and what you eat, it affects everything the body does - including taking a poo!
